摘要
分析了PDM全固态发射机天调及滤波电路,并对天线调配网络可能出现的两种情况(雷电、邻频干扰)进行可行性分析,计算出天线的归一化阻抗,通过实例对匹配网络进行实测。
This paper analysed the antenna tuner and the filtering circuit of the PDM pure solid-state transmitter,and analysed the feasibility of the two possible conditions (lightning and adjacent frequency interfe-(rence)) of the antenna matching network,works out the antenna's normalized impedance,makes the actual measurement of the matching network through the true exam.
